Description

Technical Field

[0001] This utility model relates to the field of material stacking equipment, and in particular to a stacker crane lifting structure for automated warehouses. Background Technology

[0002] Stacker cranes are key equipment in automated warehouses for the automated storage and retrieval of goods. Their main function is to run along tracks between high-rise racks and use their lifting structure, forks or gripping mechanisms to achieve precise handling and stacking of goods between different storage locations. The lifting structure of the stacker crane is the core device for realizing the vertical transfer of goods, and its operational stability directly affects warehousing efficiency and cargo safety.

[0003] In the existing technology, the lifting structure of the stacker crane usually carries the goods through the loading platform and relies on the lifting drive mechanism to drive the loading platform to complete the lifting action. When the goods are transported to the loading platform, they are positioned only by the support of the loading platform surface, and there is a lack of a specific clamping mechanism.

[0004] While some improved structures attempt to fix goods manually or limit them with simple baffles, this increases the need for manual intervention, which contradicts the high efficiency requirements of automated warehousing. Alternatively, they can only limit the horizontal displacement of goods and cannot cope with vertical vibration and impact, thus failing to completely eliminate the risk of goods falling accidentally. Therefore, a stacker crane lifting structure for automated warehouses is proposed to solve the above problems. Utility Model Content

A drive assembly is fixedly connected to the top of the L-shaped support plate 9. Multiple connecting blocks 17 are fixedly connected to the outside of the drive assembly.

A sliding assembly includes a traveling wheel a2, which is slidably connected to the outside of a lower rail 1. A sliding plate 3 is slidably connected to the inside of the lower rail 1. The traveling wheel a2 connects the sliding plate 3 to the lower rail 1. Sliding friction is converted into rolling friction. A column assembly 4 is fixedly connected to the top of the sliding plate 3. The outer right side of the column assembly 4 is fixedly connected to the left side of the motor a5. The drive assembly includes a cylinder 10. An L-shaped support plate 9 provides stable mounting support for the cylinder 10. The bottom of the cylinder 10 is fixedly connected to the top of the L-shaped support plate 9. A piston rod 11 is fixedly connected to the drive end of the cylinder 10. A platform 12 is fixedly connected to the top of the piston rod 11. The platform 12 is slidably connected to the inside of the lifting platform 8. The gripper assembly includes a rotating... Plate 16, one end of the rotating plate 16 is rotatably connected to the inside of the connecting block 17, and the other end of the rotating plate 16 is rotatably connected to an L-shaped rotating rod 14. The top end of the L-shaped rotating rod 14 is fixedly connected to a clamping claw 15. The L-shaped rotating rod 14 converts the swing of the rotating plate 16 into the opening and closing action of the clamping claw 15. The front and rear sides of the inside of the lifting platform 8 are rotatably connected to rotating shafts 13. The inside of multiple L-shaped rotating rods 14 is rotatably connected to the outside of two rotating shafts 13. The outside of the traveling wheel a2 is rotatably connected to the inside of the sliding plate 3.

[0034] Reference Figure 1 , Figure 4 , Figure 5Two horizontal support plates 24 are fixedly connected to the outer right side of the column assembly 4. A motor b25 is fixedly connected to the top of each horizontal support plate 24. An eccentric wheel 26 is fixedly connected to the drive end of the motor b25. The motor b25 adjusts the frequency and force of the pressure applied to the wire rope coil 7 by the eccentric wheel 26. The eccentric wheel 26 contacts the wire rope coil 7. A tension sensor 31 is fixedly connected to the outside of the wire rope coil 7. The tension sensor 31 monitors the tension value of the wire rope coil 7 in real time and feeds the signal back to the motor b25 in real time. The top of the sliding plate 3 is fixedly connected to... Multiple lower rubber buffers 27 are connected, which absorb the impact force when the lifting platform 8 descends by utilizing the elastic deformation of rubber. Multiple upper rubber buffers 28 are fixedly connected to the top of the column assembly 4, which provide top buffer protection. Two wire rope brakes 29 are fixedly connected to the left and right sides inside the column assembly 4. The wire rope brakes 29 brake the wire rope coil 7 in an emergency. A wire rope speed controller 30 is fixedly connected to the top of the column assembly 4, which can switch the stacker crane from high speed to low speed.

[0035] Reference Figures 1 to 3 An extension platform 18 is fixedly connected to the outer left side of the column assembly 4. A control cabinet 19 is fixedly connected to the top of the extension platform 18. The control cabinet 19 integrates electrical components such as circuit breakers, contactors, PLC controllers, and relays. Multiple vertical support plates 32 are fixedly connected to the top of the sliding plate 3. The vertical support plates 32 provide rotational support shafts for the guide wheels 20. Multiple guide wheels 20 are rotatably connected inside the vertical support plates 32. The guide wheels 20 provide guidance for the vertical lifting of the lifting platform 8. A groove 21 is opened inside the lifting platform 8. The inside of the groove 21 is slidably connected to the outside of the guide wheels 20. A traveling wheel b22 is rotatably connected inside the column assembly 4. The inside of the traveling wheel b22 is slidably connected to the outside of the upper rail 23. The traveling wheel b22 cooperates with the upper rail 23 to provide horizontal guidance for the top of the column assembly 4.

[0036] Working principle: The traveling wheel a2 in the sliding assembly rolls along the lower rail 1, while the traveling wheel b22 at the top of the column assembly 4 slides synchronously along the upper rail 23. After the control cabinet 19 issues a lifting command, the motor a5 starts and drives the drum 6 to rotate. The wire rope coil 7 retracts or releases the rope with the forward and reverse rotation of the drum 6, thereby pulling the lifting platform 8 to move vertically along the column assembly 4. When the goods are loaded onto the surface of the loading platform 12, the cylinder 10 is activated. The cylinder 10 drives the loading platform 12 to descend, thereby driving the rotating plate 16 to move downward, pulling the L-shaped rotating rod 14 to rotate around the outside of the rotating shaft 13, thereby causing the clamping claw 15 to slowly clamp the goods and prevent the goods from falling accidentally during the lifting process.

[0037] Tension sensor 31 monitors the tension value of wire rope coil 7 in real time. When the tension deviates from the set range, the signal is fed back to control cabinet 19, triggering motor b25 to drive eccentric wheel 26 to rotate. Eccentric wheel 26 periodically squeezes wire rope coil 7, and with the stable support of horizontal support plate 24, avoids tilting of lifting platform 8 due to tension imbalance.

[0038] When the lifting platform 8 descends to the lowest position, the lower rubber buffer 27 absorbs the impact energy through elastic deformation to avoid rigid collision. When it rises to the highest position, the upper rubber buffer 28 similarly plays a buffering role. If the lifting platform 8 descends at excessive speed due to a malfunction, the wire rope brake 29 quickly clamps the wire rope and locks it in an emergency. When the tension sensor 31 detects abnormal wire rope tension, the control cabinet 19 immediately stops the machine and triggers an alarm.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
